mount error: could not resolve address for Diskstation: Unknown error

[ffonz]

Hi,

I try to mount my NAS onto Ubuntu 12.04. This is my situation:

$ smbtree
WORKGROUP
    \\PX-EH                  PX-EH
        \\PX-EH\lp                 
        \\PX-EH\ADMIN$             IPC Service (PX-EH)
        \\PX-EH\IPC$               IPC Service (PX-EH)
        \\PX-EH\Guest              
        \\PX-EH\disk               LAN disk
    \\DISKSTATION            
        \\DISKSTATION\IPC$               IPC Service ()
        \\DISKSTATION\home               home
        \\DISKSTATION\homes              user home
        \\DISKSTATION\NetBackup          System default shared folder
        \\DISKSTATION\Share              DiskStation 212

Then I try this

$ sudo smbmount //Diskstation/home samba
mount error: could not resolve address for Diskstation: Unknown error

I even tried Diskstation with capitals and with non-capitals, but no success.
When I do

$ nmblookup -R -U <<IP-address>> diskstation
querying diskstation on  <<IP-address>>
 <<IP-address>> diskstation<00>

It seems there are some non-printable odd characters behind 'diskstation'.

With the PX-EH nas, I have the same problems, so it is not caused by the others side.

I don't want to type an IP-address. I want to use names, that's what they're for.

How can I mount my NAS with its name?
And if I need to add the name to some hosts file, why can I browse the samba drives with Nautilus without such a hosts file?

Hi,

I try to mount my NAS onto Ubuntu 12.04. ...I try this

$ sudo smbmount //Diskstation/home samba
mount error: could not resolve address for Diskstation: Unknown error

Where are you attempting to mount //Diskstation/home to? The location samba seems incorrect.

$ nmblookup -R -U <<IP-address>> diskstation
querying diskstation on  <<IP-address>>
 <<IP-address>> diskstation<00>

It seems there are some non-printable odd characters behind 'diskstation'.

These are part of the NETBIOS protocol. They identify the type of node (i.e server or master browser or client).

With the PX-EH nas, I have the same problems, so it is not caused by the others side.

How can I mount my NAS with its name?
And if I need to add the name to some hosts file, why can I browse the samba drives with Nautilus without such a hosts file?

I'll bet the mount command is incorrect. Where are you trying to mount //Diskstation/home to? What's the mount point?

Hi bab1,

'samba' is a directory in /mnt. So I try to be less ambiguous. Here is another attempt:

~$ sudo smbmount //Diskstation/home /mnt/samba
mount error: could not resolve address for Diskstation: Unknown error
~$ ls -l /mnt
total 4
drwxr-xr-x 2 root root 4096 Nov 12  2010 samba

Does the samba directory have the correct permissions?

The directory permissions are not a problem for mounting the share. You are having a problem resolving the name. What do you get with this command

smbclient -L diskstation

The COMPUTER name is case insensitive so caps are not needed at the CLI on Ubuntu.

Hi bab1,

This is the result:

This shows that the name is being resolved correctly. I'll bet you need to use a more current mount command. The command smbmount is part of the deprecated smbfs package. The newer package CIFS-UTIL will work better. The basic command is something like

mount -t cifs //SERVER/share /path/to/mountpoint -o options

or 

mount.cifs //SERVER/share /path/to/mountpoint -o options

See here and .here for info.

I've lost a lot of time to make ubuntu (kubuntu) cifs working with android's samba file sharing.
It works great with Krusader, but not with cifs.utils. Forum does help, but not in one place.
So I've put it all together here. Maybe it will be useful for someone else.

My errors messages was:
mount error: could not resolve address for SGN3: Unknown error
cifs_mount failed w/return code = -5
cifs_mount failed w/return code = -111
cifs_mount failed w/return code = -112


I've fixed it with this changes:

1. /etc/samba/smb.conf:
name resolve order = bcast

2. /etc/nsswitch.conf
hosts: files wins dns

3. /etc/fstab
//SGN3/sdcard /home/sergey/pda cifs username=sergey,uid=sergey,user,sec=ntlmv2 0 0

And now it works as expected:
(ku:~)$ mount pda
Password for sergey@//SGN3/sdcard:
(ku:~)$ umount pda
